IMPROVEMENT IN WAGON-BRAKES. y

Specification formingr part of Letters Patent No. 116,505, dated June27, 1871;

To all 'whom it may concern:

Be it known that I, F. WILHELM SCHULTZ, of Mount Pleasant, in the countyof Henry and in the State of Iowa, have invented certain new and usefulImprovements in Wagon-Brakes; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereonmaking a part of this specification.

The nature of my invention consists in the construction and arrangementof a wagon-brake, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and op eration, referring to the annexed drawing, in which-Figure l is a bottom view of a wagon-frame, showing my brake, and thevarious devices connected therewith, attached to the same.` Figs. 2 and3 are views of detached portions, and Fig. 4 shows a modification ofthedevices connected with the tongue of the wagon.

A represents the front axle, and .B the rear axle, connected by theperchpole C. D is the tongue; E, the double-tree; G G, singletrees; andH, the neck-yoke; all constructed in any of the known and usual ways.The neck-yoke H is attached to the tongue I) by means of a loop orstaple, a, which allows it 'to slide back and forth on the tongue for ashort distance. It is connected, by a hook or link, with a lever, I,pivoted in the front end of the tongue. The lower end y of this leveris, by a rod, I), connected with the yoke J, which slides in guides onthe under side `of the front axle A. The rea-r end of the yoke J is, bya rod, d, connected with a 'ba-r, K, from which rods c c-connect withlevers L L, pivoted in guides on the under side of a cross-barconnecting the rear hounds. The other ends of the levers L L are, byrods f f, connected with the brake-block M, which is hung or suspendedun# der the rear hounds, from the lock-bar N, by the loops or rods h h.`The connection between the rod d and bar K is made adjustable by anysuitable means, so that it can be changed to suit any length of wagon.When the horses are held or stopped the neck-yoke H slips back on thetongue, and, through the various devices above described, draws thebrake-bar M toward the rear, so that the shoes will bear against thehind wheels. P represents the brake-block or shoe, the back of which `ismade at an angle to the face, and is held in its place by the guide k,which is made so as to fit in grooves or slots in the block; and whenthe wagon backs the wheel raises the brake-block up and frees itself;but as soon as started forward it will fall into its place.v Forreleasing the brake from the wheels, chains t' 'i are attached to theunder sides of the whiffletrees Gr G, said chains being` attached tolevers O O, pivoted on the under side of the front axlev A, and theselevers, by other chains, m m, connected with a lever, R, on the yoke J.By this means, as soon as the horses start, the brake-bar is moved awayfrom the wheels. The same ob ject may be accomplished by the deviceshown in' Fig. 4, which device I shall probably adopt for permanent use.In this case the lever l is not pivoted in the front end of the tongue,but the lower end is forked and placed over the tongue, a pin throughthe same passing through a slotted iron attached to the tongue, so that,by pulling the neck yoke back, the lever slides a short distance andthen turns. The rod b', attached to the 'forked ends of the lever I',connects with a lever, S, pivoted in the rear end of the tongue, and theupper end of said lever connected with the double-tree E', whichisarranged so that it can slide back and` forth a short dis-` tance uponthe tongue. The rod b also connects with the yoke J, and, by thisarrangement, when the horses pull forward on the double-tree, the brakeis released. In either case I may, as an auxiliary, employ a spring, n,attached to the front side of the rear axle B, and connected by a hook,P, with the/plate K, which will have a tendency to draw the brake-baraway. from the wheels'. Y

This brake is applicable to any and every description of four-wheeledvehicles.

. Havingthusfullydescribedmyinvention,what I claim as new, and desire tosecure by Letters Patent, is t l. The combination ofthe lever I', rodb,'-lever S, and sliding double-tree E', substantially as and for thepurposes herein set forth.

2. The combination of the singletrees G G, chains vi 'i and m m, levers0 O and R, and yoke J, all substantially as and for the purposes hereinset forth.

.3. The combination of the lever I or I', rod b, yoke J, rodv d, bar K,rods e c, levers L L, rods f j', and brake-bar M, all constructed andarranged substantially as and for the purposes herein set. forth.

4. The spring u and rod p, connected With the bar K, and operating.substantially as and for the purposes herein set forth.

5. The brake-block P, constructed as described,

and sliding up and dovlvn in the guide k on the brake-bar, substantiallyas and for the purposes herein yset forth.

In testimony that Iv claim the foregoing I have l hereunto set my handand seal this 24th day of April, 1871.
